Abstract:

This article presents the properties of magnetic fibres and the opportunities to use them in the construction of textile magnetic elements. Magnetic fibres belong to the group of multifunctional fibres, as independently of their natural textile features they are characterised by new properties which increase their range of possibilities for use in textronic products. The properties of magnetic fibres depend on the kind of magnetic material (the filler) included in the fibre matter, as well as on the filling degree. The degree of filling the fibre with grains of magnetic materials also influences its mechanical properties. Magnetic fibres may be used for the construction of textile magnetic coils. A magnetic coil, with or without a magnetic core, is the basic element of magnetic circuits which consist of parts of electric and electronic circuits. These circuits are in turn parts of various electromagnetic devices, such as inductive gauges and transmitters, as well as electromagnets which form the basis for electromagnetic actuators.
